研究了导体背衬共面波导的色散和辐射特性。使用使用 PML 吸收边界条件的频域有限差分法。识别了不同类型的高阶模式，并给出了避免寄生效应的设计规则。发现辐射比无限地面宽度小得多。
Dispersion and radiation properties of the conductor-backed CPW are studied. A frequency-domain finite-difference method using the PML absorbing boundary condition is used. The different types of higher-order modes are identified and design rules to avoid parasitic effects are given. Radiation is found to be considerably smaller than for infinite ground width.
